REVOLVING TABLE FOR TILE-MILLS.

SPECIFICATION forming part of Letters Patent No. 300,909, dated June 24, 1884.

Application filed May .29. 1885!. (No model.)

To all whom it may concern..-

Be it known that I, JOHN S. SMITH, of the city of Jackson, county of Jackson, and State of Michigan, have invented certain new and useful Improvements in Revolving Tables for Tile-Mills, of which the following is a specifi-- cation.

My said invention consists in a revolving table mounted upon an axis, the wings where of are severally adapted to receive the tile as it issues from the mill and then be advanced, and a catch or means of holding said table at the points severally where it is desired that it shall stop, as will be presently more fully described.

It further consists in the combination, with a tile-mill, of a revolving table, the surface of one side of the wings whereof is concave and the other flat. It does not, however, consist, broadly, in the combination, with a tile-mill, of a revolving table adapted to receive the tile on their sides as they issue horizontally from the mill and afterward raise them on end; nor of such a table one side of each arm whereof is formed to act as a rest for the newly-formed tile, and the other to sustain a pallet or plate on which the tile shall be received as the table revolves.

Letters Patent No. 267,760, dated November' 21, 1882, having been issued on an application which was a division of this case, the subj cot-matter of said application is of course included in this specification; but it will be understood that such subject-matter forms no part of the invention herein claimed.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1 is a side elevation of a machine embodying my improvements; Fig. 2, a top or plan view thereof; Fig. 3, an end elevation, as seen from the dotted line 00 x in Fig. 1; Fig. 4, a section of the upper frame on the dotted line y y in Fig. 2; Figs. 5, 6, and 7, views of the interior supporting-drum, and Fig. 8 a detail view of the spring-catch and one of the wings of the table while in engagement therewith.

The machine, or the parts thereof essentially intended to carry out my invention, may

be combined with a tile-mill of any of the wellknown forms, or with one of any preferred character. It may be mounted upon a frame-work of any suitable character more or less different from that shown.

In the drawings, I have shown a main supporting-frame constructed of the uprights or legs A A, the sills or longitudinal pieces B B, and the cross-pieces G O. The legs or supports A A may be permanently fastened to the other parts of the frame, or they may be detachably connected thereto, and also may be made in such manner that the height of the machine can be adjusted upon them. Upon this frame is mounted another, adapted to be moved up and down to a limited extent, the

latter frame consisting of the side pieces, A,

and two or more cross-pieces, B B. These two frames are connected by means of links a n and curved connecting arm or bar N. The said bar is slotted, as at n, and pivoted at n to the upper frame, there being a set-screw, n in the slot n, by which the frameA B may be supported in any desired position.

N is an adjustable handle carried by the this frame is mounted a transverse shaft, D. 85v

To the shaft are secured four wings, E E E E, or recessed plates, they being situated at, substantially, ninety degrees apart. At one end of the frame A B there is arranged a cut-off It is conmechanism. Preferably it consists of an arched 0 plate, F, provided with aslot, f, and the wirecarrying arm G. The wire 9 is so arranged that as the arm or handle G is caused to traverse the arched plate F the wire cuts the tube of clay and forms a tileiof the proper 5 7 length. In the construction shown in the drawings, the wire has its lower end attached to an eye, 9, which is connected by a hinge with the spring 9 the spring being arranged to yield somewhat, so that when the wire IOO comes in contact with small stones or other hard substances in the clay the wire may yield sufficiently to prevent a marring of the tile. At the upper end 'the wire is attached to an eye or hook, h, at the lower end of a threaded rod, 71.. This threaded rod is held in the carryingarm G, which is provided with a longitudinal aperture to receive it.

h is a thumb-nut engaging by thread con-. nection with the rod If, and by means of it the tension of the wire may be delicately adjusted. The wire-carrying arm G is cast with or secured to a curved plate, G, which conforms as accurately as possible to the outer face of the arched-plate IF, it being formed with lugs or ears 7L5, which are turned down and under the plate F, to provide a clamp to hold the plate F in place. The inner end of the wirecarrying rod h movesback and forth in the slot f. However, I do not limit myself to this. exact form of cutter, for some of the features of my machine may be embodied without its being restricted to this form of cutter, though I find that my form possesses advantages when combined in the way shown with the parts to be hereinafter, described.

Before the tile is cut the frame A B is moved up into proper position relatively to the tile-mill. As the tile issues from the mill it is deposited upon the trough or curved plate E,that has been brought up to receive it. It moves along said trough or plate until it strikes against a removable plate, I, that is placed against the back of the wing E, which is in a vertical position. After it strikes against the vertical plate I, the upper frame moves relatively to the lower frame, and the tile is then out. As soon as cut the shaft D is revolved one-quarter of a revolution, which brings the tile from the horizontal position into the vertical position, it resting, after being brought into the vertical position, upon the removable plate I. It can be readily taken away while standing vertically by removing the platemI, which has now been brought into a horizontal position. Throwing the tile into the vertical position, and with it the wing E, with which it is in contact, brings the next wing or curved plate into a horizontal position proper to receive the next tile. Before the succeeding tile has been entirely received upon the Wing, the upper frame should be removed back into its original position relatively to the tile-mill.

It will be seen that the four wings E E E E form a revolving table, and that each part of the table in turn receives a tile in' a horizontal position and raises it on end before it is removed from the table. With the revolving table I combine a spring-catch which operates to stop the table in a proper position to receive the tile, and which can be withdrawn to permit the next movement of the table. I have shown in the drawings one form of spring -catch, though others will readily suggest themselves, adapted to perform substantially the same operations. The one shown consists of a laterally-moving piece, J, which permits the plates successively to come up to a horizontal position, and a lateral part, J, which prevents them from rising above said position until it (said part J) has been intentionally withdrawn by the operator. The part J of the stop prevents the plates from moving downward while they are receiving the tiles. Both of these parts J J may be made in one piece of metal, as will be readily understood. For some purposes, however, I prefer to construct them separately, as shown, and provide each of them with an independent spring, part J being beveled or having its inner lower edge rounded, so as to permit the upward movement of theparts of the revolving table, it (said part J) moving out of the path until the plate or trough has passed it, and then moving again below the plate or trough, this movement being caused by the spring j. The part J is held across the path of the plate or wing by means of a spring, jr. spring-catch is thus constructed and arranged, I mount the parts thereof in a bracket-piece, K, carried by the frame which supports the table.

To prevent the platesor wings from being worn away by the action of the springcatch, I provide each of them with wearingplates k k, so situated that when the catch engages with the plates the contact shall be received by them.

With the revolving table I (to get the best results) combine a stationary table or trough, L, so situated as to first receive the tile as it issues from the mill and before it is cut. It is secured in position by means of angle-irons ll, which are slotted, as at l, to receive the clamping-screws I, whereby the trough L is secured to the frame. If vertical adjustment is necessary, it is permitted by the slots 1. As the tile issues from the mill, I insert into the end thereof a detachable cylinder or drum, M, of suitable length, the external diameter of which is substantially the same as the internal diameter of the pipe or tube of clay. I leave it there until the tile has been turned upon end, after which I draw the drum through the tile from the end into which it was inserted to the other. The objects of this are,

When the first, to keep the end of the tile from flattening as it runs along the trough; and, secondly, to form a perfect cylinder of clay and remove or clean away the ragged edges that are generally left by the wire on the inside of the tile, in this way obviating the tedious process of trimming or finishing with a knife that is now necessary. The revolving table is adjustable in the rolling-frame which carries it, the adj ustment being effected by means of slots d din the side pieces of the frame, and the shaft D, which can be moved in said slots and secured in different positions by means. of clampingnuts d d.

The drum or cylinder M is preferably constructed as shownthat is, with heads m m and slats m, fastened thereto. In order to draw it easily through the tile, a handle may be attached to it, as shown in Figs. 4 and 5, or a separate handle may be used in withdrawing it, as shown in Fig. 7; but I do not limit myself to the use of such handles, as the purposes-of the drum can be accomplished without such a device.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a tile-mill, a frame, a revolving table mounted in said frame, and catches secured to said frame, and adapted to engage with and hold the wings of said table.

2. In a tile-mill, the combination of the revolving table consisting, essentially, of wings mounted on an axis, and a spring-catch, said wings being arranged to be consecutively caught and retained by said catch.

3. The combination,with the revolving table consisting of wings E, provided with wearingplates 7c, of a catch for holding the table, said plates being arranged to come in contact with said catch as the table revolves.

4. The combination, with a revolving table, of a catch consisting of a bracket, K, and spring-pins mounted therein, substantially as set forth.

5. The combination, with the wings of a revolving table for tile-mills, of a catch consisting, essentially, of two spring-mounted pins, J and J, substantially as described, and for the purposes specified.

6. The combination, with a revolving table for tile-mills, consisting, essentially, of wings to receive the tile, coming together at a com- JOHN S. SMITH.
